A gas leak monitoring system according to an embodiment of the present disclosure may be easily applied to a laboratory or the like to which a large amount of gas is supplied and also may detect a gas leak economically and efficiently. In addition, according to an embodiment of the present disclosure, it is possible to immediately check a gas leak and take a measure through a user terminal or a management module to prevent a large accident caused by the gas leak in advance.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A gas leak monitoring system, comprising: a supply tubing equipped with a supply valve; a gas supply unit configured to be connected to the supply tubing to supply the gas to the supply tubing; a pressure sensing module configured to detect a pressure of the gas in the supply tubing and output real-time tubing pressure data; a database (DB) module configured to save the real-time tubing pressure data and normal tubing pressure data; a server module configured to analyze the real-time tubing pressure data and the normal tubing pressure data transmitted from the DB module, determine a gas leak state when the real-time tubing pressure data deviates from the normal tubing pressure data, and perform different safety actions according to conditions of the supply tubing; and a management module configured to receive gas leak data from the server module; wherein, in a state where the supply tubing is closed by the supply valve, the server module transmits the gas leak data to the management module when the real-time tubing pressure data which is the pressure of the gas remaining in the supply tubing deviates from the normal tubing pressure data determined as a preset constant value; and in a state where the supply tubing is opened, the server module closes the supply tubing by the supply valve when the real-time tubing pressure data which is the pressure of the gas moving through the supply tubing deviates from the normal tubing pressure data which is average value of the plurality of pressure values measured during the preset time; and wherein the gas supply unit comprises a gas storage unit in which the gas is stored, a residual gas detecting unit configured to measure a residual gas of the gas storage unit and apply a gas supplement notification signal to the sever module when the gas supply amount falls below the preset supply amount.
2. The gas leak monitoring system according to claim 1 , wherein the pressure sensing module is provided in plural in predetermined regions of the supply tubing based on the supply valve; and the server module analyzes the normal tubing pressure data and the real-time tubing pressure data for each predetermined region.
3. The gas leak monitoring system according to claim 2 , wherein, when the real-time tubing pressure data of at least one of the predetermined regions deviate from the normal tubing pressure data in a state where the supply tubing is closed by the supply valve, the server module transmits the gas leak data of the at least one of the predetermined regions to the management module.
4. The gas leak monitoring system according to claim 2 , wherein, when the real-time tubing pressure data of at least one of the predetermined regions deviate from the normal tubing pressure data in a state where the supply tubing is opened, the server module closes the supply tubing of the at least one of the predetermined regions by the supply valve.
